Poldaw Windpump = Traditional
Concept + Modern Design |
|
| · Handpumps These are preferred for relatively modest water needs but are usually limited to depths of up to about 50 metres. The Poldaw Windpumps can pump from as much as 140m. |
| · Electric / diesel pumps Either requiring a mains supply (not always available in remote locations) or a diesel engine with a regular fuel supply, these pumps have high servicing and maintenance overheads. Poldaw Windpumps run on free energy and only require simple annual preventative maintenance. They do not require operator attention on a day-to-day basis. |
| · Solar pumps These can be an attractive option in good sunlight locations but they are an expensive investment (usually imported) and also are prone to damage and theft. Poldaw Windpumps can be manufactured locally with local materials and are robust and difficult to steal! |
| Poldaw Windpumps are a practical solution and will operate in winds as light as 2.5 to 3 metres per second (approx. 5 to 7 mph). A reasonable sized storage tank ensures water is available even on windless days. (Other powered pumping methods also usually employ storage tanks). |
